RAILWAY TBIP DEVICE.

Patented Oct. 4, 1910.

Application filed October 11, 1909. Serial No. 522,001.

T 0 all whom it may concern:

Be it known that I, ALBERT l /l. downs, a citizen of the United States,and a resident of Hagerstown, in the county of Washington and State ofMaryland, have made certain new and useful Improvements in Railway TripDevices, of which the following is a specification.

My invention relates to devices for use on railway tracks for engaging amovable part on an engine or train for actuating a train stoppingmechanism, andit consists in the combinations, arrangements and construetions herein described and claimed.

An object of my invention is to provide a device by which a tappct orother projecting portion connected with a valve stem on an engine maybepositively moved to effect the stopping of the train. To this end Iprovide a trip adapted to be raised or lowered, of

suflicient length to insure the positive action of the emergency valve.

A. further object of my invention is tor provide means for raising orlowering the trip which do not involve the use or springs but whichconsist of a pinion and rack, thus insuring the positive action of themechanism.

it further object of my invention is to provide means by which the tripdevices may lie-raised in case of breakage of the op eratin r wires orrods.

Other objects and advantages will appear in the following specificationand the novel features of the device will be particularly pointed out inthe appended claims.

My invention is illustrated in the accompanying d rawings, in which--Figure 1 is a. plan view of the device; Fig. 2 is a side elevation; lig. El is a section along the line 3-3 of Fig. 21; Fig. -1 a sectionalong the line d-l of Fig. 2; and Fig. a section along the line 5-4; ofFig. 2.

In carrying out my invention 1 provide a main casing 1 of the shapeshown in the figures. One end of the casing is deeper than the other,see Fig. 2, and this endis secured to the end of a railroad tie 8 bymeans of a lug 2 and bolt 9;. The opposite end is secured to theadjacent tie 1 by means of a lug 5 and bolt 5'.

The trip proper consists of a bar 6 which is pivotally connected to theend members 7 and 8 respectively. These latter members are slotted as at7 and 8 to receive the pins 9 and 10, respectively. The central portionof member (Sis slotted at 11, see Figs. 1 and 3, to receive the tongue12 of a slidable rack member, being secured to the latter by means ofthe screw 14:. This rack member has an inner portion 13 arranged toslide between the side members of the frame 1 and an outer portion 13upon which the teeth 15 of the rack are secured. The rack member isslotted at 17 as shown in Fig. 3 so as to permit it to slide up anddown, being guided in its movement by a portion of the casing 1.

Pivoted. onthe outside of the casing 1 is a bell-crank lever 18 whichrotates about a point- 19 and bears on one end a gear section 20 havingteeth arranged to mes with the teeth 15 of the rack. The opposite end ofthe bell-crank lever is pivotally attached to a pull-rod 21 whichextends to the switch tower or other place for operating the trip. Thelever 18 is limited in its movement by the stop bar 22 which is securedto the side of-the casing 1 by the bolts 28.

Pivotally secured to an extended portion 13 of the rack is one end 24 ofalever 24 which is rotatably mounted on a bolt 25 between the lugs 26and 97 of the frame 1. The bolt 25 has a shoulder 25 and is held inposition by means of a nut 28. On the bar 2th is a weight-29 which isadjustably secured to the bar by means of the set screw 3.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood.

The device as stated before, is designedto be placed along a railroadtrack so as to engage a movable tappct 31 for forcing the latteri'ipward and operating a train valve. The means by which a train isstopped is disclosed in a prior Patent No. 941,259 of Nov. 23, 1909, andforms no part of the presout invention. When it is desired to raise thetrip in position to engage the tappet, the rod 31 is moved in thedirection shown by the arrow in Fig. 1, thereby turning the lever ltl onits pivot and causing the gear 20 to force the l attcr upwardly therebyraisin the contact bar 6 and causing the ends 7 an 8 to be slightlydrawn inwardly. The device is held in this position by locking means atthe switch tower. Now when the tappet 31 comes in contact with theinclined ends 7 or 8 it rides up these ends on to the horizontal contactmember 6 which is of sufiicient length to insure the absolute upwardmovement of the tappet and the operation of the valve. I The trip may belowered by moving the rod 21 in the opposite direction thus bringing thecontact arms into line as shown in Fig. 1. In case the operating rod 21on the lever 18 should break, the weight 29 will cause the upwardmovement of the trip so that there is little danger of the trip failingto Operate. The weight may be moved along the bar 24: so as to obtainthe desired lever age.-

I claim:

l. A railway trip device comprising a casing, a contact member slidablysecured thereon, inclined arms pivotally secured at the ends of saidcontact member said arms being slidably supported and means for movingsaid contact member into and out of operating position.

2. A railway trip device comprising a casing, a rack slidably mountedthereon, a con- .tact member secured to said rack, inclined zoiital-barsecured to the upper end of said rack, inclined arms pivotally securedat the pivoted to said casing and provided with a gear section arrangedto mesh with the teeth on said rack and a pull-rod for operating saidgear section.

4. A railway trip device comprising a casing, pins carried thereby, arack slidably mounted'thereon, having a portion arran ed to slide withinsaid casing and an exten ed portion adapted to project outside of saidcasing, a contact bar secured at the top of said rack, arms pivotallysecured at the ends of said contact bar, said arms being slotted toreceive said pins and adapted to slide on the latter, a bell-crank leverpivoted on the exterior portion of said casing and provided with a gearsection on one end arranged to mesh with theteeth on said rack, apull-rod for operating said lever, an emergency lever pivotally mountedwithin said casing and having one end pivotally con- 4 nected with saidrack and an adjustable weight secured to the opposite end of said secondlever for operating said rack.
